US President Donald Trump and Israeli Prime Minister Benjamin Netanyahu agreed at a White House meeting this week to increase economic pressure on Iran, including efforts to curb its oil exports to China, Axios reported.

The understanding, reached during talks on Wednesday, would form part of a renewed “maximum pressure” campaign running alongside indirect nuclear negotiations with Tehran, according to two US officials briefed on the discussions.

“We agreed that we will go full force with maximum pressure against Iran, for example, regarding Iranian oil sales to China,” a senior US official said.

China buys more than 80% of Iran’s oil exports, making it Tehran’s main source of crude revenue. Any significant reduction in those purchases would sharply increase economic strain on Iran and could affect its calculations in nuclear talks with Washington.

An executive order signed by Trump earlier this month allows the administration to expand economic measures against Iran. The order authorizes the secretaries of state and commerce to recommend tariffs of up to 25% on countries that conduct business with Iran.
